“Regardless of how may times she had to all 911, you know this was the one time that really really mattered and they were not there for her,” Cook-Gundy said.

Cook made the call from her cell phone at her southern Dallas home. The officers who arrived at her home 50 minutes later left after no one answered the door.

Cook’s worried relatives, including Cook-Gundy, found her dead body in a bathtub of the flooded home two days later. Patrick, 35, faces a murder charge in the case. He has a history of beating and threatening Cook.

The sisters were asked whether they believe Cook, 32, could have been saved if Dallas police had responded faster.

“Something could have been done if they responded immediately,” Battle said. “My nieces wouldn’t have had to find their mother. That would make a huge difference. My sister and my mother wouldn’t have had to see it. That would have made a huge difference.”
